A 36-year-old man has been charged with blowing up two Pacific Gas & Electric transformers, causing blasts that knocked out power to thousands of utility customers in the San Francisco Bay Area.

Peter Karasev was arrested last Wednesday after investigators used surveillance camera footage and cell phone tracking to link him to the explosions in December and January, according to the San Jose Police Department.

It wasn't immediately known if he has an attorney who could speak on his behalf.

Authorities on Friday searched Karasev's home and turned up explosive materials along with an "inactive" meth lab, police said.

No injuries were reported in the blasts on Dec. 8 and Jan. 5 that damaged two PG&E transformers, KGO-TV reported.

Karasev faces multiple charges including arson, exploding a destructive device, destroying an electrical line and possessing materials with the intent to create a destructive device, the Santa Clara County District Attorney's Office said.

Karasev made his initial court appearance on Friday and was ordered to return April 26. He’s being held without bail.

A woman performing in the picturesque "Voladores" ritual has died after falling from the 30-yard high pole, authorities in the central Mexico state of Puebla confirmed Sunday.

The municipal government in the city of Huauchinango said it was cancelling the remaining festivities in a sign of mourning.

The performers were apparently from a troupe of mainly female "voladores." They had been performing at the city’s Festival of Flowers when the accident occurred Saturday night.

The cause of the accident is under investigation.

The voladores, or flyers in English, are generally four performers who climb up the pole and tie themselves to ropes twisted around the pole; they then leap outwards and descend through the air, moving in circles as the rope unwinds.

While the best-known voladores are from Papantla, in the neighboring state of Veracruz, the act, which originated as a spiritual observance, is also performed in Puebla.
